To all whom it may concern: and to accomplish this, it is necessary thatBe it known that I, Samrox BmwnLL, of the gas before it enters theburner must be the city of Chicago, county of Cook, and regulated, sothat the How will be according State of Illinois, have invented a newand to the pressure.

To this handle ismode of operating the cock by the spring attached rod Z), and spring a.b the rod, exand diaphragm, by the pressure of the gas, tends up to thediaphragm, and the spring a, in the regulator as coi'istructed. extendsdown to the screw a to which it is 15 Figure 1, is an exterior sideelevation. attached, and which screw is capable of Fig. 2, is a verticalsection.
